2024-06-21selftest: af_unix: Add Kconfig file.Kuniyuki Iwashima
diag_uid selftest failed on NIPA where the received nlmsg_type is NLMSG_ERROR [0] because CONFIG_UNIX_DIAG is not set [1] by default and sock_diag_lock_handler() failed to load the module. # # Starting 2 tests from 2 test cases. # # RUN diag_uid.uid.1 ... # # diag_uid.c:159:1:Expected nlh->nlmsg_type (2) == SOCK_DIAG_BY_FAMILY (20) # # 1: Test terminated by assertion # # FAIL diag_uid.uid.1 # not ok 1 diag_uid.uid.1 Let's add all AF_UNIX Kconfig to the config file under af_unix dir so that NIPA consumes it.

2024-06-20selftests/bpf: Add client_socket helperGeliang Tang
This patch extracts a new helper client_socket() from connect_to_fd_opts() to create the client socket, but don't connect to the server. Then connect_to_fd_opts() can be implemented using client_socket() and connect_fd_to_addr(). This helper can be used in connect_to_addr() too, and make "noconnect" opts useless.

2024-06-20selftests/bpf: Drop type from network_helper_optsGeliang Tang
The opts.{type, noconnect} is at least a bit non intuitive or unnecessary. The only use case now is in test_bpf_ip_check_defrag_ok which ends up bypassing most (or at least some) of the connect_to_fd_opts() logic. It's much better that test should have its own connect_to_fd_opts() instead. This patch adds a new "type" parameter for connect_to_fd_opts(), then opts->type and getsockopt(SO_TYPE) can be replaced by "type" parameter in it. In connect_to_fd(), use getsockopt(SO_TYPE) to get "type" value and pass it to connect_to_fd_opts(). In bpf_tcp_ca.c and cgroup_v1v2.c, "SOCK_STREAM" types are passed to connect_to_fd_opts(), and in ip_check_defrag.c, different types "SOCK_RAW" and "SOCK_DGRAM" are passed to it. With these changes, the strcut member "type" of network_helper_opts can be dropped now.

Introduce a new 'of-fullname-regex' property that takes a regular expression and matches against the OF_FULLNAME property. It allows matching controllers that don't have a unique DT address across sibling controllers, and thus dt-mmio can't be used. One particular example of where this is needed is on MT8195 which has multiple USB controllers described by two level deep nodes and using the ranges property: ssusb2: usb@112a1000 { reg = <0 0x112a1000 0 0x2dff>, <0 0x112a3e00 0 0x0100>; ranges = <0 0 0 0x112a0000 0 0x3f00>; xhci2: usb@0 { Signed-off-by: Nícolas F.

2024-06-19binfmt_elf: Honor PT_LOAD alignment for static PIEKees Cook
The p_align values in PT_LOAD were ignored for static PIE executables (i.e. ET_DYN without PT_INTERP). This is because there is no way to request a non-fixed mmap region with a specific alignment. ET_DYN with PT_INTERP uses a separate base address (ELF_ET_DYN_BASE) and binfmt_elf performs the ASLR itself, which means it can also apply alignment. For the mmap region, the address selection happens deep within the vm_mmap() implementation (when the requested address is 0). The earlier attempt to implement this: commit 9630f0d60fec ("fs/binfmt_elf: use PT_LOAD p_align values for static PIE") commit 925346c129da ("fs/binfmt_elf: fix PT_LOAD p_align values for loaders") did not take into account the different base address origins, and were eventually reverted: aeb7923733d1 ("revert "fs/binfmt_elf: use PT_LOAD p_align values for static PIE"") In order to get the correct alignment from an mmap base, binfmt_elf must perform a 0-address load first, then tear down the mapping and perform alignment on the resulting address. Since this is slightly more overhead, only do this when it is needed (i.e. the alignment is not the default ELF alignment). This does, however, have the benefit of being able to use MAP_FIXED_NOREPLACE, to avoid potential collisions. With this fixed, enable the static PIE self tests again. Reported-by: H.J.

2024-06-19selftests/exec: Build both static and non-static load_address testsKees Cook
After commit 4d1cd3b2c5c1 ("tools/testing/selftests/exec: fix link error"), the load address alignment tests tried to build statically. This was silently ignored in some cases. However, after attempting to further fix the build by switching to "-static-pie", the test started failing. This appears to be due to non-PT_INTERP ET_DYN execs ("static PIE") not doing alignment correctly, which remains unfixed[1]. See commit aeb7923733d1 ("revert "fs/binfmt_elf: use PT_LOAD p_align values for static PIE"") for more details. Provide rules to build both static and non-static PIE binaries, improve debug reporting, and perform several test steps instead of a single all-or-nothing test. However, do not actually enable static-pie tests; alignment specification is only supported for ET_DYN with PT_INTERP ("regular PIE").

2024-06-19selftest/cgroup: Update test_cpuset_prs.sh to match changesWaiman Long
Unlike the list of isolated CPUs, it is not easy to programamatically determine what sched domains are being created by the scheduler just by examinng the data in various kernfs filesystems. The easiest way to get this information is by enabling /sys/kernel/debug/sched/verbose file to make those information displayed in the console. This is also what the test_cpuset_prs.sh script is doing when the -v flag is given. It is rather hard to fetch the data from the console and compare it to the expected result. An easier way is to dump the expected sched-domain information out to the console so that they can be visually compared with the actual sched domain data. However, this have to be done manually by visual inspection and so will only be done once in a while. Moreover the preceding cpuset commits also change the cpuset behavior requiring corresponding chanages in some test cases as well as new test cases to test the newly added functionality.

2024-06-19selftest/cgroup: Fix test_cpuset_prs.sh problems reported by test robotWaiman Long
The test robot reported two different problems when running the test_cpuset_prs.sh test. # ./test_cpuset_prs.sh: line 106: echo: write error: Input/output error # : # Effective cpus changed to 0-1,4-7 after test 4! The write error is caused by writing to /dev/console. It looks like some systems may not have /dev/console configured or in a writeable state. Fix this by checking the existence of /dev/console before attempting to write it. After the completion of each test run, the script will check if the cpuset state is reset back to the original state. That usually takes a while to happen. The test script inserts some artificial delay to make sure that the reset has completed. The current setting is about 80ms. That may not be enough in some cases especially if the test system is slow. Double it to 160ms to minimize the chance of this type of failure.

2024-06-17selftests: mptcp: userspace_pm: fixed subtest namesMatthieu Baerts (NGI0)
It is important to have fixed (sub)test names in TAP, because these names are used to identify them. If they are not fixed, tracking cannot be done. Some subtests from the userspace_pm selftest were using random numbers in their names: the client and server address IDs from $RANDOM, and the client port number randomly picked by the kernel when creating the connection. These values have been replaced by 'client' and 'server' words: that's even more helpful than showing random numbers.

2024-06-17lkdtm/bugs: add test for hung smp_call_function_single()Mark Rutland
The CONFIG_CSD_LOCK_WAIT_DEBUG option enables debugging of hung smp_call_function*() calls (e.g. when the target CPU gets stuck within the callback function). Testing this option requires triggering such hangs. This patch adds an lkdtm test with a hung smp_call_function_single() callback, which can be used to test CONFIG_CSD_LOCK_WAIT_DEBUG and NMI backtraces (as CONFIG_CSD_LOCK_WAIT_DEBUG will attempt an NMI backtrace of the hung target CPU). On arm64 using pseudo-NMI, this looks like: | # mount -t debugfs none /sys/kernel/debug/ | # echo SMP_CALL_LOCKUP > /sys/kernel/debug/provoke-crash/DIRECT | lkdtm: Performing direct entry SMP_CALL_LOCKUP | smp: csd: Detected non-responsive CSD lock (#1) on CPU#1, waiting 5000000176 ns for CPU#00 __lkdtm_SMP_CALL_LOCKUP+0x0/0x8(0x0). | smp: csd: CSD lock (#1) handling this request. | Sending NMI from CPU 1 to CPUs 0: | NMI backtrace for cpu 0 | CPU: 0 PID: 0 Comm: swapper/0 Not tainted 6.9.0-rc4-00001-gfdfd281212ec #1 | Hardware name: linux,dummy-virt (DT) | pstate: 60401005 (nZCv daif +PAN -UAO -TCO -DIT +SSBS BTYPE=--) | pc : __lkdtm_SMP_CALL_LOCKUP+0x0/0x8 | lr : __flush_smp_call_function_queue+0x1b0/0x290 | sp : ffff800080003f30 | pmr_save: 00000060 | x29: ffff800080003f30 x28: ffffa4ce961a4900 x27: 0000000000000000 | x26: fff000003fcfa0c0 x25: ffffa4ce961a4900 x24: ffffa4ce959aa140 | x23: ffffa4ce959aa140 x22: 0000000000000000 x21: ffff800080523c40 | x20: 0000000000000000 x19: 0000000000000000 x18: fff05b31aa323000 | x17: fff05b31aa323000 x16: ffff800080000000 x15: 0000330fc3fe6b2c | x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000279 | x11: 0000000000000040 x10: fff000000302d0a8 x9 : fff000000302d0a0 | x8 : fff0000003400270 x7 : 0000000000000000 x6 : ffffa4ce9451b810 | x5 : 0000000000000000 x4 : fff05b31aa323000 x3 : ffff800080003f30 | x2 : fff05b31aa323000 x1 : ffffa4ce959aa140 x0 : 0000000000000000 | Call trace: | __lkdtm_SMP_CALL_LOCKUP+0x0/0x8 | generic_smp_call_function_single_interrupt+0x14/0x20 | ipi_handler+0xb8/0x178 | handle_percpu_devid_irq+0x84/0x130 | generic_handle_domain_irq+0x2c/0x44 | gic_handle_irq+0x118/0x240 | call_on_irq_stack+0x24/0x4c | do_interrupt_handler+0x80/0x84 | el1_interrupt+0x44/0xc0 | el1h_64_irq_handler+0x18/0x24 | el1h_64_irq+0x78/0x7c | default_idle_call+0x40/0x60 | do_idle+0x23c/0x2d0 | cpu_startup_entry+0x38/0x3c | kernel_init+0x0/0x1d8 | start_kernel+0x51c/0x608 | __primary_switched+0x80/0x88 | CPU: 1 PID: 128 Comm: sh Not tainted 6.9.0-rc4-00001-gfdfd281212ec #1 | Hardware name: linux,dummy-virt (DT) | Call trace: | dump_backtrace+0x90/0xe8 | show_stack+0x18/0x24 | dump_stack_lvl+0xac/0xe8 | dump_stack+0x18/0x24 | csd_lock_wait_toolong+0x268/0x338 | smp_call_function_single+0x1dc/0x2f0 | lkdtm_SMP_CALL_LOCKUP+0xcc/0xfc | lkdtm_do_action+0x1c/0x38 | direct_entry+0xbc/0x14c | full_proxy_write+0x60/0xb4 | vfs_write+0xd0/0x35c | ksys_write+0x70/0x104 | __arm64_sys_write+0x1c/0x28 | invoke_syscall+0x48/0x114 | el0_svc_common.constprop.0+0x40/0xe0 | do_el0_svc+0x1c/0x28 | el0_svc+0x38/0x108 | el0t_64_sync_handler+0x120/0x12c | el0t_64_sync+0x1a4/0x1a8 | smp: csd: Continued non-responsive CSD lock (#1) on CPU#1, waiting 10000064272 ns for CPU#00 __lkdtm_SMP_CALL_LOCKUP+0x0/0x8(0x0). | smp: csd: CSD lock (#1) handling this request. | smp: csd: Continued non-responsive CSD lock (#1) on CPU#1, waiting 15000064384 ns for CPU#00 __lkdtm_SMP_CALL_LOCKUP+0x0/0x8(0x0). | smp: csd: CSD lock (#1) handling this request.

2024-06-15selftests: mm: make map_fixed_noreplace test names stableMark Brown
KTAP parsers interpret the output of ksft_test_result_*() as being the name of the test. The map_fixed_noreplace test uses a dynamically allocated base address for the mmap()s that it tests and currently includes this in the test names that it logs so the test names that are logged are not stable between runs. It also uses multiples of PAGE_SIZE which mean that runs for kernels with different PAGE_SIZE configurations can't be directly compared. Both these factors cause issues for CI systems when interpreting and displaying results. Fix this by replacing the current test names with fixed strings describing the intent of the mappings that are logged, the existing messages with the actual addresses and sizes are retained as diagnostic prints to aid in debugging.

2024-06-14bpf: Track delta between "linked" registers.Alexei Starovoitov
Compilers can generate the code r1 = r2 r1 += 0x1 if r2 < 1000 goto ... use knowledge of r2 range in subsequent r1 operations So remember constant delta between r2 and r1 and update r1 after 'if' condition. Unfortunately LLVM still uses this pattern for loops with 'can_loop' construct: for (i = 0; i < 1000 && can_loop; i++) The "undo" pass was introduced in LLVM https://reviews.llvm.org/D121937 to prevent this optimization, but it cannot cover all cases. Instead of fighting middle end optimizer in BPF backend teach the verifier about this pattern.
